To all whom it may concern-.-

Be it known that I, GEORGE W. Bnownn, a citizen of the United States ofAmerica, and a resident of 27a Second street, Portland, county ofMultnomah, State of Oregon, have invented certain new and usefulImprovements in Sawmills, of which the following is a specification.

My invention relates to sawmills, and has for its object to provide aportable sawmill, to provide sawing mechanism adapted with the greatestfacility to cut a log into a great number of sections of any size ordimension desired, to provide mechanism for setting the sawing mechanismat the position desired, to provide an electric motor mounted on themill fordriving the sawing mechanism, and to provide a mill which issimple and inexpensive in construction and effective in operation.

To these ends my invention consists in the construction, combination,and arrangement of parts more fully hereinafter described and claimed.

My invention is illustrated by the accompanying drawings, in which-Figure 1 is a top plan view. Fig. 2is a bottom plan view. Fig. 3 is aside view, and Figs. 4 and 5 detail views of the eccentric wheel.

Referring to the accompanying drawings,

in which like characters of reference indicate like parts throughout theseveral views, A designates the framework, comprising cornerposts B,side beams 0, connecting the upper ends of said posts, and side beams D,connecting the lower ends thereof. E E are shafts journaled in the upperends of the posts B, having a miter-gear F mountedin each end and amiter-gear G near one en H is a shaft journaled in the upper part of theframe A, having miter-gears I on each end meshing with miter-gears G.

J represents vertically movable frames, comprising beams K K, connectedat each end by blocks L, interposed between the same.

M represent-s strips attached to the sides of beam K, and N representsracks on the under sides thereof.

Orepresents flanged rails on the upper surfaces of beams K, and Prepresents rails on the upper surfaces of beams K.

Q represents screwthreaded sleeves secured to the under sides of blocksL.

R represents vertical screw-threaded rods which engage the sleeves Q andhave mitergears S mounted on their upper ends meshing with gears F.

T is a horizontally-movable frame comprising beams U U and cross-beamsV, connecting the same.

W represents flanged rails on the upper surfaces of beams U U, and W isa rack on the under surface of the beam U.

a represents truss-braces located adjacent to the outside of the beams UU, one of which has brackets 17 secured to its ends.

0 represents axles journaled in the brackets I), having flanged wheelsd, secured on their outer ends, adapted to ride on the tracks P.

6 represents grooved rails attached to the under side of the beams U U,at each end, adapted to engage the rails 0.

f is a horizontally-movable carriage mounted on the frame T, comprisingend beams g, cross-beams h h 72 h connecting the same, and upright posts2'. I

j represents grooved wheels mounted on shafts 7o, journaled in posts 7;.

Zis a shaft journaled in the frame of the carriage f, on one end ofwhich is secured a pinion Z, engaging the rack W.

Z is an eccentric supported in a box 1 and loosely mounted on the outerend of the shaft Z and having a lever Z attached thereto.

Z is a large friction-wheel keyed to the shaft Z and provided with acircular groove i", having contacting surfaces Z and Z m is a motormounted vertically on the carriage f, the shaft of which projects belowthe frame T and has a circular saw a secured thereto. 0 is another motormounted horizontally on said carriage, the shaft 1'0 of which projectslaterally on both sides and has a circular saw q secured to one end anda frictionwheel on its other end, engaging the circular groove Z offriction-wheel F.

s is a shaft journaled in brackets t, secured to the frame '1 and havinga pinion-wheel 26 on each end, engaging the racks N. o is aratchet-wheel also mounted on the shaft .9.

w is a lever having a pawl 2 engaging the ratchet 1; for the purpose ofoperating the same to turn the shaft 3.

3 is a pin adapted to be inserted through 3. lug 4 and into one end of aseries of holes in the lever w for the purpose of setting the shaft 8 inthe desired position.

5 is a pulley-wheel on the opposite end of the shaft 8. 6 is a rope, oneend attached to said pulley-wheel and the other end adapted to beconnected to the carriage f by means of a hook 6*, on the end thereof,engaging an eye 7 on the carriage.

8 9 represent beams comprising a skid upon which the logs to be out aredrawn into the mill.

10 is a cable provided with a grapplinghook 11, adapted to be driveninto a log, any suitable power being applied to the other end of thecable for hauling the log into the mill.

12 is a cog-wheel on shaft E, adapted to receive power from any suitablesource for operating the vertical shafts R to raise and lower the frameJ. V

I do not limit myself to the precise construction and arrangement hereinshown and described, as the same may be varied somewhat withoutdeparting from the spirit of my invention.

The operation is as follows: One end of the cable 10 is secured to thelog to be cut and by means of power applied to the other end of thecable the log is drawn into the mill. The lever Z is thrown to theright, shifting the eccentric Z secured thereto, and the friction-wheelZ to the left, which causes the friction-wheel r to contact with thesurface i of the friction-wheel Z The motor 0 is now started, andthrough the medium of the friction-Wheel r, mounted on the shaft of saidmotor, the friction-wheel Z and its shaft Z and pinion-wheel Z arerotated to the right, and the pinion-wheel Z being in engagement withthe rack W the carriage is also moved to the right to the positiondesired at one end of the log to be cut. The gear-wheel 12 on shaft E isthen caused to rotate by power applied thereto turning its shaft andthrough the medium of the miter-gears F on each end thereof engaging themitergears S on the shaft R and miter-gears G near each end of saidshaft engaging the miter-gears I on the shaft H the shaft R is turned,and in turning raises or lowers the frame J, thus raising or loweringthe carriage and the saws thereon to the height desired. The shaft 3,mounted in brackets 15, attached to the frame J, is then turned by thepawl and ratchet mounted therein, and through the medium of thepinion-wheel u on its end engaging the racks N on the under side of thestrip M the frame T is moved back or forth, thus bringing the carriageand the saws thereon to the position desired. Everything being now inreadiness for sawing, the carriage is moved forward by the motor 0 andcuts a slab off the log. The lever Z is now thrown to the left, whichreverses the movement of the pinion Z and the carriage is moved back tothe position from which it started. To place the saws in position to sawoff another slab, the frame T is moved to the right by turning theratchetwheel 1;, which revolves the shaft e and causes pinionwheel u tomove along on rack N. This operation is continued until the surface ofthe log has been sawed off fiat. To saw off another section of the log,the rope 6, connected to pulley-wheel 5, is connected to the carriage f,and the carriage, by means of the motor 0, is moved back to the positionfrom which it started, and by means of the rope 6, connect ing thecarriage with the pulley on shaft e, the frame T is moved therewith toits original position.

Having thus described my invention, what I claim isl.
